novel means for delivering whole width or slitted sheets flat eithersuccessively or in groups. p

My invention includes means for cutting sheets from a traveling web, arotary sheet carrier which may be a slitting cylinder, an endless webfeeding carrier which engages the web, carries it through the sheetcutting means and transfers the sheets cut therefrom to said rotarysheet carrier; a sheet delivery;

device which may be an endless delivery carrier and'a rotary transfercylinder arranged to transfer the sheets from the rotary sheet carrierto the endless delivery carrier.

My invention more specifically includes means whereby the cylinder whichtransfers the sheets from'the rotary sheet carrier to the sheet deliverydevice may be used either as a means for transferring successive sheetsfrom the rotary sheet carrier to the delivery device or it may be usedas a collecting cylinder for collecting thereon successive whole widthor slitted sheets as the case may be, and transferring the collectedgroup of sheets to the delivery device, a movable cam being arranged toopen the transfer cylinder grippers every second revolution of thetransfer cylinder at'the point of transfer to the grippers of'thedelivery device, friction pulleys being employed for holding the firstwhole width or slitted sheets on the transfer cylinder inproperregisterwhile the grippers are open to receive the second whole width or slittedsheets. I V

A practical embodiment of my inventionis represented in the accompanyingdrawings,

in which Fig. 2 is a detail section taken from front to rear just insidethe near side frame,

Fig. 3 is a detail section showing the cams for operating the transfercylinder grippers, V

' cated withln the path of the endless carrier and Fig.4 is adiagrammatic section taken from front to rear centrally through thedelivery mechanism.

The web is fed at a certain speed between the rolll and rollers 2. Themeans for cutting sheets from the traveling webis shown as apair ofrotary cutters 3, 4, mounted on suitable shafts 5, 6, and having one setof coactingblades 7, 8. r

The sheet receivingtable is denoted by 9. A sheet delivery device isarranged to depositthe full width or slitted sheets either, successivelyor in groups upon the table 9, which delivery device is herein shown asan endless sheet delivery chain carrier 10 having head grippers 11arranged at intervals along the same.

A rotary sheet carrier, in the present instance a slitting cylinder 12,is mounted upon provided with two sets of grippers 14, 15.

The means for transferring the sheets from the cylinder 12 to the sheetdelivery device, is shown as a rotary cylinder 16 mounted on a shaft 17and having a single set of grippers 18. 'Friction pulleys 19 hearingagainst the periphery of the transfer cylinderl6 are shown as mounted inyielding arms 20 carried by fixed arms 21 on the cross shaft 22.

A'curved sheet guide 23 is also provided partway around the periphery ofthe transfer cylinder 16. I

An endless web feeding carrier, which is shown herein as an. endlesschain carrier 23, has, at intervals thereon, side grippers 24 carried tograsp the side edges of the web before the web reaches the rotarycutters 3, 4, carry the web through said rotary cutters and finallytransfer the heads of the sheets cut from the web to the grippers 14 or15 of the cylinder 12. Guides 25, 26, serve to guide the web from thefeed roll to the rotary cutters and a guide 27 serves to support thesheets from the rotary cutters to the cylinder 12. Y I

"A rotary sheet tucker 28 is mounted on a shaft 29 within the path ofthe endless car- 23 and. the carrier is herein shown as down- Wardlyinclined from the web roll 1 to a point beyondthe cylinder 12.

The side grippers 24 are operated by fixed cams 30 at the proper pointto grasp the side edges of the web near thebeginning of the rectilinearportion of their travel away from the receiving end: of the endlesscarrier.

Fixed cams 31 are arranged in position to open the side grippers 24 nearthe end of the rectilinear portion of their travel toward the deliveryend of the carrier at the proper time to transfer the sheets cut fromthe web to the grippers on the cylinder 12.

' A fixed cam 32 is arranged in position to successively operate thegrippers 14, 15, of the cylinder 12 to cause them to close upon theheads of successive sheets as they are fed from the endless carrier 23and a fixedcam 33 is arranged in position to open the grippers'totransfer the heads of the sheets to the grippers 18 of the transfercylinder 16.

A fixed cam 34 is arranged in position to operate the grippers 18 of thetransfer cylinder to cause them to receive successive sheets from thegrippers 14, 15, ofthe cylinder 12.

A cam 35 is carried by one arm of a rock lever 36 pivoted at 37, theother arm of which lever is provided with a stud or roller 38 travelingin the groove 39 of a rotary box cam 40 mounted on a shaft 41.

A gear 42 is carried by the box cam 40 and a gear 43 is mounted on theshaft 17 of the transfer cylinder. When the transfer cylinder isutilized fortransferringsuccessive sheets from the cylinder-12 to the.endless delivery carrier 10, the gears 42 and 43 are placed out ofmesh, thus holding the cam 35 stationary. Whenthe transfer cylinder isusedfor collecting successive. sheets, in the present instance two, fromthe cylinder 12 and transferring the group of sheets to the grippers 11of the endless delivery carrier, the gearsv 42 and 43v are brought intomesh so that the cam 35 is moved into position to open the transfercylinder grippers 18 every second revolution thereof, at their point oftransfer to, the endless delivery carrier.

A fixed cam 44 is arranged in position to operate the successive headgrippers 11 of the endless delivery carrier to cause themv to receivethe heads vof the, sheets from the transfer cylinder grippers 18.

A fixed cam 45 is arranged in position to operate the head grippers .11to cause them to release the heads of the sheets-at the proper time fordelivery onto the sheet receiving table 9. h

It is to be understood that where two sheets are collected on thetransfer cylinder alternatehead grippers :on the .endlessdeliverycarrier may-be removed.

, Where the sheets are to beslit longitudinally of their travel into aplurality of sheets, one or more slitting disks 46 may be provided inposition to slit the sheets onthe cylinder 12.

The geared connection between the several parts is as follows: Theshaft13 of the cylinder 12 is driven through the train of gears 47, 48, 49,50. The rotary cutters are driven from the gear 48 through the gear 51and the endless web feeding carrier 23 has its side chains exteriorlytoothed and driven by gears 52 on the shaft 5 of the rotary cutter 3 atthe speed of the traveling web. The transfer cylinder shaft 17 is drivenfrom the cylinder shaft 13 through the gears 53, 54. The endlessdelivery carrier 10 is driven from the gear 54 through the gears 55,5'6, 57. The shaft 58 of the slitter 46 is driven from the shaft 13through thegears 53,59. The shaft 29 of'the rotary tucker is driven fromthe shaft 13 through the gears '53, 610.

The geared connection between'the several parts is such that thecylinder 12 has a surface speed slightly higher than the speed of thetraveling web and of the surface speed of' the web feeding endlesscarrier. The transfer cylinder and the endless delivery carrier have thesame surface speedas the cylinder 12. This cylinder 12 has each of itssheet carrying surfaces at little longer than the sheet thereby leavingan open space between the sheets sufficient to permit the coaction ofthe transfer cylinder grippers with the grippers on the cylinder 12 whentakingthe sheets from said cylinder.

In operation: The side grippers of the endless web feed engage the sideedges of the traveling'web at the speed thereof and carry the webthrough the rotary cutters where the sheet is cut from the web. Theseside grippers feed the head .of the sheet to the grippers on thecylinder 12, the rotary tucker 28 insuring the accurate grasping of thehead "of'the sheet by saidgrippers on the cylinder 12 absolutelysquarewith the side.

edges of the sheet; If desired, the sheetlis slit longitudinally ,of itstravel on the cylinder 12 and the slit sectionsare then trans ferred tothe transfer cylinder grippers 18. If the sheet is not to be slit, thewhole width sheet is transferred to the said grippers 18. The wholewidth or slitted, sheets are transferred successively to the headgrippers 11 of theendlessdelivery carrier 10 or, if so desired,'thewhole Width or slitted sheets may be collected by the grippers 18 intogroups and the groups transferred to the head grippers 11 In the former;instance, the cam 35 is held stationary byputting the gears 42, 43, outof mesh and'in the latter instance this cam is rendered movable byputting the said gears into mesh.

Thehead grippers, 11 deliver the whole width or slitted sheets onto thesheet receivingtable 9. V r

WVhile'I have shown the sheets as slit'into pairs, it is obvious thatthe sheets maybe dinally into any number ofsmaller sheets,

asdesired.

It is also to be seen that'the sheets either whole width or slitted, maybe delivered successively or in groups, as desired;

' By the term cylinders wherever used, I wish to include any meanssuitable for carrying the sheets through the prescribed paths and by theterm grippers I wish to include any means suitable for engaging thesheets to lead them through their path of travel.

By maintaining control of the sheet after it is cut from the web untilit is positively engaged by the grippers on the cylinder 12, I amenabled to feed the sheet with its head absolutely square with respectto its side edges so as to insure the accurate slitting of the sheetparallel with said side edges when it is desired to slit the sheets.

Furthermore, by the use of the endless web feeding carrier, for feedingthe web through the cutters and then transferring the sheet cuttherefrom to the slitting cylinder, the mechanism for handling the weband sheets is materially simplified.

It is evident that changes might be resorted to in the form,construction and arrangement of the several parts without departing fromthe spirit and scope of my invention; hence I do not Wish to limitmyself strictly to the structure herein set forth, but
